When we do get it sold we would like to take back out the amount we bought it for and the money we put into it (we do not have a mortgage on it we bought it in cash and did all the repairs with cash).  

My question is if the purchase price is $50k and I need 100k for repairs is it 25% of just the puchase price or is it 25% of the purchase and rehab total?

Repairs/CapEx/Vacancy projections might be a little low.You should budget for property management, even if you're planning to self-manage.

It would cashflow and is huge and big has potential Purchase would be $16,000 buying as is. 5 bedroom 2.5 baths sold as is needs work and cleaned out. thinking $10-15k repairs to make it rent.

I would also get some advice about the value, condition and cost to repair.

At the top of the chimney, it's cracking and needs repaired, but otherwise in good shape. 

I typically do not ask buyers to make repairs or do anything to the property both because of this and because they'll do it the cheapest and laziest way possible.

The calculator made me estimate my repair budget, but even if that number holds over the long run, I have no idea whether I spend more of it up front or later on, and if I keep that money in an interest-bearing account, that will impact how much it grows.The calculator is a great starting point, but like any tool, you need to understand how to use it.

If she won't go down in price, then have her pay some of your closing because it appears you are paying market price according to the auditor's site.Also, your rent should go up with up with that much repair.  

I would be supplying the purchase price and the repair cost of this home   Once everything has been completed I need my purchase price back and repair costs back.
